Definitions

  • the invention relates to an energy guiding chain with a first chain section having a plurality of chain links and a second chain section having a plurality of chain links, wherein the chain links of the two chain sections are pivotally connected to one another and each comprise two side parts which are opposite one another in a transverse direction to the longitudinal direction of the energy guiding chain and which have upper and lower narrow surfaces pointing perpendicular to the transverse direction and the longitudinal direction, wherein at least some of the chain links have cross members connecting their side parts and at least some of the chain links of the first chain section have guide elements which protrude outwards from their side parts in the transverse direction for guiding the chain links on or on guide tracks which can be arranged on the outside of their side parts, and at least some of the chain links of the second chain section have roller elements or sliding elements which protrude over the upper or lower narrow surfaces of their side parts and can roll or slide on an area which is opposite these narrow surfaces and which contacts the energy guiding chain.
  • the chain links are provided with sliding shoes which protrude outwards from their side parts transversely to the longitudinal direction of the chain and have standing surfaces. Some sliding shoes each have a recess which is designed for the engagement of a guide roller which can be arranged on the outside of the chain, whereby the guide rollers engage in the recesses of the relevant sliding shoes of the lower run and serve as guide tracks for guiding the upper run on standing surfaces of the sliding shoes.
  • the chain links adjoining the chain links provided with the recesses in turn have a sliding shoe provided with a roller or a sliding shoe provided with a projection which interact with opposite rollers and projections of the relevant sliding shoes in overlapping chain areas of the upper and lower run.
  • the energy chain known from this document is, as described above, suitable for arrangement in the form of a loop with a lower strand connected to a stationary connection point and an upper strand running above it and guided on the guide rollers.
  • the known chain is unsuitable for cases in which the strands of one or more loops are to be moved in a guiding manner when moving the energy chain, especially if the chain is to be able to be stored in a guided manner in the form of several consecutive loops in a storage unit, for example a storage unit .
  • the present invention is based on the object of providing an energy chain of the type mentioned at the outset, which comprises one or more adjacent loops, the strands of which are connected by a deflection area along external guide tracks and along themselves contacting areas or external contact surfaces can be guided with the lowest possible frictional forces.
  • the object is achieved according to the invention by the combination of features of claim 1 in that the total width of the chain links of the second chain section in the transverse direction is less than or equal to the total width of the chain links of the first chain section minus the width in the transverse direction of the guide elements extending on the outside.
  • the second chain section In the event that when the energy chain is moved, the second chain section reaches an area in which guide tracks are arranged for the external guidance of the first chain section, the second chain section is not hindered by the guide tracks in this area.
  • the second chain section can be moved past the guideways due to its correspondingly smaller width.
  • the two chain sections can be connected to one another in an articulated manner.
  • the energy chain according to the invention can consist exclusively of the first and the second chain section.
  • the energy guiding chain according to the invention can have several alternating first and second chain sections.
  • the roller elements or sliding elements of the second chain section can be arranged in the longitudinal direction in alignment with the narrow surfaces of the side parts of the chain links of the first chain section, so that the roller or sliding elements of a region of the second chain section can roll or slide on the narrow surfaces of the side parts of an area of the first chain section.
  • a chain link is arranged between the two chain sections, the side parts of which have an outwardly bent area and an inwardly bent area, the outwardly bent area being connected to the longitudinally adjacent side part of the first chain section and the inwardly bent area are articulated to the side part of the second chain section adjacent in the longitudinal direction.
  • the side parts of the chain links of the first chain section and/or the second chain section, which are adjacent in the longitudinal direction, alternately consist of inner and outer plates are formed.
  • the inner and outer tabs have overlapping areas, with the overlapping areas of the outer tabs being arranged on the outside of the overlapping areas of the inner tabs.
  • the guide elements of the chain links of the first chain section are designed as guide rollers.
  • two guide rollers can be arranged on the outside of the outer plates of the chain links of the first chain section.
  • two roller elements can be arranged on the outside of the outer plates of the chain links of the second chain section.
  • Adjacent chain links of the energy chain can be angled to a limited extent relative to one another in a pivoting direction by stops, whereby a minimum radius for the deflection bends of the deflection areas of the energy chain is defined. Furthermore, they can be angled to a limited extent in the other pivoting direction up to their mutually stretched orientation. Since adjacent chain links in this case cannot be pivoted beyond their mutually stretched alignment, a relatively stable straight extension of the same is made possible, particularly in the case of essentially self-supporting strands.
  • the invention further relates to a storage unit for an energy chain.
  • the storage unit comprises a storage housing and an energy chain arranged therein according to the present invention with the features described above.
  • the energy chain comprises a first chain section of the type described above and an adjoining second chain section of the type described above and is wound spirally in the storage housing with two winding axes whose distance from one another is variable. At one end it has a fixed connection point arranged stationary in the storage housing inside the spiral winding and at the other end it has a movable connection point, whereby the distance between the winding axes from one another can be changed between a minimum distance and a maximum distance by moving the movable connection point and thereby moving the energy guide chain.
  • the first chain section is connected to the movable connection point and the second chain section is connected to the fixed connection point.
  • the fixed connection point is preferably arranged in the central region of the storage housing based on its longitudinal extent in the longitudinal direction of the strands.
  • a storage unit of the type mentioned above is particularly suitable for storing an energy chain in a relatively long available storage space, so that the maximum distance between the two winding axes can be selected to be relatively large in relation to their minimum distance.
  • the storage housing has two parallel side plates which are arranged parallel to the deflection bends of the deflection areas of the energy chain and which extend in the longitudinal direction of the strands over the deflection areas of the energy chain on both winding axes.
  • the movable connection point is arranged outside the storage housing.
  • a through-opening for the run of the first chain section of the energy guiding chain connected to the movable connection point can be provided between the side plates in their upper or lower areas.
  • the side plates of the storage housing have opposite guide tracks on their insides, which cooperate with the guide elements projecting outwards on the chain links of the first chain section.
  • the guide tracks extend in one or more windings in a spiral shape on the inside of the side plates around two winding axes, which correspond to the winding axes of the energy chain arranged at their maximum distance.
  • the length of the guide tracks wrapped around their stationary winding axes is adapted to the length of the first chain section of the energy chain. When retracted into the storage housing, the first chain section of the energy chain can extend over the entire length of the guide tracks.
  • the adjoining second chain section of the energy chain then extends with at least one deflection area around at least one of the winding axes arranged at their maximum distance to the fixed connection point and lies with its side pointing radially outwards in relation to the deflection area over the roller elements or sliding elements on the first chain section.
  • the energy chain with its first chain section is pulled out of the storage housing through the feed-through opening, the area of the first chain section stored spirally in the storage housing along the guide tracks unwinds.
  • the chain links of the second chain section adjoining the first chain section are wound up in a spiral shape without being hindered by the guide tracks, with the distance between their winding axes reduced to their minimum distance in the area of the fixed connection point.
  • an element supporting the inner winding can be provided.
  • the guide tracks arranged on the inside of the side plates of the storage housing can be designed as guide rails on which the guide elements projecting outwards on the chain links of the first chain section slide or roll.
  • roller elements or sliding elements of the chain links of the second chain section protrude from the narrow surfaces of the side parts of the chain links which are radially outer with respect to the deflection areas and thus roll or slide on the radially inward-facing sides of the chain links which contact them.
  • the energy guide chain can therefore be pulled out of the storage housing with a relatively low tensile force on the strand connected to the movable connection point and inserted into the storage housing in the longitudinal direction with a relatively low compressive force on the strand connected to the movable connection point.
  • the tensile and compressive force can optionally be exerted manually on the strand connected to the movable connection point and extending out of the storage housing.
  • an opening can be provided in at least one side plate of the storage housing for the passage of the cables emerging from the energy chain.
  • the storage housing can have end plates at the front ends of the side plates and upper and lower end plates connecting these to each other.
  • the upper and lower end plates can be arranged in such a way that they slidably guide the upper and lower strands of the energy chain arranged in the storage housing.
  • the storage housing can be formed from two housing shells, the separating surface of which lies in a plane that extends parallel to the deflection bends of the deflection areas of the energy chain.

  • the chain links 4 of the second chain section 5 have roller elements ( Figures 1-5 ) or sliding elements ( Figures 9-13 ) which protrude beyond the upper narrow surfaces 8 of their side parts 6, 7 according to the drawing figures and which can roll or slide on an area opposite these narrow surfaces 8 which contacts the energy guide chain 1 (not shown in the figures mentioned).
  • the total width b2 of the chain links 4 of the second chain section 5 in the transverse direction, including the roller elements 13 or sliding elements 14, is equal to the total width b1 of the chain links 2 of the first chain section 3 minus the guide elements 12 extending on the outside, i.e. the width of the area of the guide elements 12 that interacts with the guide tracks.
  • the roller elements 13 or sliding elements 14 of the second chain section 5 are arranged in the longitudinal direction aligned with the narrow surfaces 8 of the side parts 6, 7 of the chain links 2 of the first chain section 3, so that the roller elements 13 or sliding elements 14 of a region of the second chain section 5 can roll or slide on the narrow surfaces 8 of the side parts 6, 7 of an area of the first chain section 3.
